SAD-morn SPECIFICATION forming part of Letters Patent No. 700,444, dated-May 20, 19'0'2.

Application filed July 19, 1901.

class which are heated by a blast of mixedair and gas interi'orly applied, and it is flesigned as an improvementon the structure covered by my Letters Patent No. 666,115, dated January 15, 1901.V The object of the'invention is to provide a device of this'character which com prises novel features of utility, durability, and'general efzo fectivenfess, vembodying means foreve'nly heating the iron throughout the entire area of its smoothing-surface- In the accompanying drawings, forming part of this specification, Figure 1 is a longi-Y tudinal sectional elevation' of my improved iron. Fig. 2 is a cross-sectional elevation taken on aline fr of Fig. 1. Fig. 3 is an inverted plan view of a delector forming part of ithe invention, and Fig.A 4 is a sectional 3o View of the burner havingits parts disconnected.

The body Aof the iron is supplied with a recess A', open at the top and back. Formed interiorly around the top edge of the side Walls of the body A is a channel a, adapted to engage the lid or topB of the iron.

The open or rear end of the iron is closed by means of a swinging door O, pivotally secured between the side walls ofthe iron-body.

At the rear end of the iron, formed in the upper surface of the bottom thereof, is a groove a' for-receiving a burner, which will be hereinafter described. At the inner end of this said groove a convex surface or shoulder d2 is formed, which contacts with the flame from the burner.`

For supplying theheating agent to the iron 1 employ a burner E, which embodies the centrally-located Vertical duct e and the horizon- 5o tal duct e, the burner dependingfrom and Serial' No. 6 8,877. (No model.)

' forming an integral part of the removable top or coverB, whereby it can be readily removed, with the cover, for the purpose of cleaning. The'ontlet or discharge end of the d-uct e is enlarged in diameter, whereby an A lannula'r shoulder 2 is formed for contact With a wire-gauze disk 4, which is held within the annular groove 3.

The top or cover B of the iron embodies the plates b and b' and theintegrally-formed pil- 6o lars h2, b3,b3,and b4, wherebya strong structure is provided, which has an ample air-space 1 .to prevent overheating the handle B',` which also preferably forms an integral part of the jcover B. The pillars b2 bs b3 are each pierced 65 'wit-hopening-s for engaging fastening-screws `F,which are threaded into lugs A2, formed integrally with the bodyA within the recess A. VThe vertical or inlet duct e of the burner E .leads intoV a vertically-extended channel e2, 7o formed in the pillar b4, and this said channel communicates with anangularly-extended Located ii'l front of' theburner E is a con- 8o .Y

caved segmental hood or deector L. This delector is semicircular in end elevation, embodying an larch covering the endof the burner E and having the-recesses Z for lateral discharge of iiame, thebase of the arch resting upon the loorof the `recess A at its outer end, but the sides-cut away to form openings Z' for escape of ame around the deector to afford an even distribution of heat. As a further means for distributing the flame, 9o a rib Z2 is extended downwardly and centrally from the deiiector L. The inner end of the deflector L is supplied with an extended base portion L', which rests onthe ioorjof-.therecess A and engages the fastening-screw. M, which is threaded into the bas'eof the ironbody A.

.The disks 4, forming part of the burner E, are formed of malleable Wire-gauze, and they are normally of a concaved contour, having a roo diameter equal to the enlarged discharge part of the outlet of the duct e. To attach the disk to the burner, said disk is placed against the shoulder 2, with the concavity inward. Then a cylindrical tool embodying a metallic rod of a diameter equal to the outlet of the duct c' is forced against the convex surface of the disk, whereby said disk is fiattened, increased in diameter, and forced Within the annular groove 3, where it is efectually and securely retained. Any suitable number of disks may be employed, depending upon the width of the groove 3; but for purposes of illustration I have shown but one.

Located Within the channel a, between the body of the iron and the lower edge of the lid B, is a strip of asbestos P, which makes a flame-tight joint to retain the heat. This packing is placed within the channel a in a wet or moistened state, and it is then tightly compressed by lneans of the screws F to maintain a perfectly-tight joint.

In the operation and use of the invention a flexible supply-pipe of any adapted construction and'lcomposition is attached to the nozzle G and led to any suitable mixing and air-compressing apparatus adapted to supply a blast of gas and air to the iron. The burner is then lighted and the door closed, whereby the device is ready for use, and the novel relative arrangement of the burner and deflector andthe relative arrangement of the discharge end ofthe burner and the grooved bottom of the iron causes a continuous and even distribution of the projected flame.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

l. As a blast-iron, the combination, of the recessed body having a groove in its bottom, the interior channel around the upper edge of its walls and which is open at the top and rear end, the removable cover embodying the upper and lower plates having the air-space and the integrallyformed pillars between them,tl1eintegralburner embodying theinletchannel, the Vertical duct and the horizontal discharge-opening having the annular shoulder and annular groove for engaging a screen,

and the asbestos packing between the body and cover; with the arched deflector having the central rib, the bottom openings and the front recesses, substantially as shown and described.

2. As a blast-iron, the combination, with the recessed body having a groove in its bottom, an interior channel around the upper edge of its walls and which is open at the top and rear end, the removable cover embodying the upper and lower plates having the air-space and the integrally-formed pillars between them, the integral burner embodying the inlet-channel, the vertical duct and the horizontal discharge-opening having the annular shoulder and contiguous annular groove, and a malleable and normally concaved woven-wire disk within the said groove, and lying flat against the said shoulder; of an arched deiiector having openings for discharge of flame on its bottom edges and recesses also for discharge of ilame on its front edge and havinga central rib for splitting the flame, substantially as shown and described.

3. As a blast-iron, the combination, of the recessed body having the interior channel around the upper edge of its walls and which is open at the top and rear end, and means for closing the rear opening, and the removable cover embodying the upper and lower plates having the air-space and the integrallyformed pillars between them, the integral burner embodying the inlet-channel, the vertical duct andthe horizontal discharge-opening having the annular shoulder and the contiguous annular groove for engaging a screen, with the arched detlector having the central rib, the bottom openings and the front recesses, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 18th day ot July, 1001.

CHARLES II. SHEFTALL.
